About Porthleven
Porthleven is a notoriously powerful, high-consequence right-hand reef break situated adjacent to the harbour wall on the south coast of Cornwall, United Kingdom. The bathymetry is defined by a shallow, highly uneven slate rock ledge that drops abruptly into deeper water. This sudden depth transition flawlessly intercepts robust south-westerly winter groundswells travelling up the English Channel. When the swell encounters the shallow rock shelf, it pitches violently to produce a thick, immensely powerful, top-to-bottom plunging barrel immediately upon take-off. A north-easterly offshore wind is necessary to hold the heavy lip open. Due to the extreme hydraulic power, the unforgiving nature of the jagged slate base, and the highly concentrated, steep take-off zone, Porthleven is strictly reserved for advanced surfers. The wave demands rapid, precise positioning and elite tube-riding proficiency to navigate the high-speed section before the wave closes out dangerously close to the harbour wall.

How often is this page updated?
Current conditions refresh every 6 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.
What is the luck factor?
We compare the 7-day forecast to the last 5 years of marine data for the same week at Porthleven. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late April.
How is 'best session' picked?
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.
Where does the data come from?
Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).
Does the score capture local knowledge?
Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
